An application (or process) may have an amount of steady state work to perform per unit time, as well as one or more mechanisms for doing a lower quality job of that work in the event the application falls behind. Approaches presented herein can utilize a clock monitor that enables the application to determine whether a clock loss was encountered that was due to an external source, and is of an amount of time that may be naturally recoverable by the application. If so, the application can enter into a mode of operation wherein the activation of one or more recovery mechanisms is postponed for a period of time to provide the application time to recover. If, after the period of such mode operation, the application has not recovered from the real time clock loss, then the recovery mechanism(s) can be activated as appropriate.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The computer-implemented method of claim 1, wherein actions of the overdrive mode include at least one of discarding a subset of data to be processed, processing only a portion of the data, or performing less processing of the data for the time-sensitive task.
5. The computer-implemented method of claim 1, wherein the time-sensitive task is executed using instructions from an application executing on a processor of a computing device, and wherein the reference clock source operates independent of the application on the computing device.
7. The computer-implemented method of claim 6, wherein actions of the enhanced recovery mode include at least one of moving a workload to another server, restarting the application, notifying a network operator, or removing a resource from service.
10. The system of claim 8, wherein actions of the overdrive mode include at least one of discarding a subset of data to be processed, processing only a portion of the data, or performing less processing of the data for the time-sensitive task.
12. The system of claim 8, wherein the time-sensitive task is executed using instructions from an application executing on a processor of a computing device, and wherein the reference clock source operates independent of the application on the computing device.
14. The system of claim 8, wherein actions of the enhanced recovery mode include at least one of moving a workload to another server, restarting the application, notifying a network operator, or removing a resource from service.
17. The non-transitory computer-readable media of claim 15, wherein actions of the overdrive mode include at least one of discarding a subset of data to be processed, processing only a portion of the data, or performing less processing of the data for the time-sensitive task.
19. The non-transitory computer-readable media of claim 15, wherein the time-sensitive task is executed using instructions from an application executing on a processor of a computing device, and wherein the reference clock source operates independent of the application on the computing device.
